The invention relates to a paving or revetment (1) comprising a top surface, such as a wearing course or a dike revetment, and a conveying element (3, 4, 6, 7, 8, 9) for conveying a liquid, such as water, along the top surface and for the transfer of heat between the top surface and the liquid. The paving (1) is characterized in that it comprises a top layer (5) with a porous layer (4) beneath which has at least 20% voids. A closed sealing layer (3) is placed beneath the porous layer (4). The liquid conveying element (3, 4, 6, 7, 8, 9) comprises in the longitudinal direction a discharge element (7, 8) and a supply element (6, 9), both of which connect to the porous layer (4) for the conveyance of liquid through said layer (4). The paving (1) according to the present invention forms a cheap solar collector which is entirely composed of materials which are in standard use in roadbuilding for paving roads. The system is relatively efficient, is easily overlaid and can be reused during replacement, renovation and other alterations of the top surface.

L'invention se rapporte à un système de pavage ou de revêtement (1) qui comprend une surface supérieure, telle qu'un revêtement de surface ou un revêtement de chaussée, et un élément transporteur (3, 4, 6, 7, 8, 9) pour acheminer un liquide, telle que l'eau, le long de la surface supérieure, et assurer le transfert thermique entre la surface supérieure et le liquide. Le système de pavage (1) se caractérise en ce qu'il comprend une couche supérieure (5) posée sur une couche poreuse (4) comportant au moins 20 % d'espace vide, elle-même posée sur une couche d'étanchéité fermée (3). L'élément transporteur de liquide (3, 4, 6, 7, 8, 9) comprend, dans le sens longitudinal, un élément de décharge (7, 8) et un élément d'approvisionnement (6, 9), tous deux reliés à la couche poreuse (4) pour assurer l'acheminement du liquide à travers cette dernière (4). Le système de pavage (1) de l'invention forme un capteur solaire bon marché et entièrement composé de matériaux couramment utilisés dans la construction de routes pour le pavage des chaussées. Ce système est relativement efficace, facilement revêtu, et peut être réutilisé pendant le remplacement, la rénovation ou d'autres modifications de la surface supérieure.
